Science and technology: Space exploration: Dusting yourself down

科技:空间探索:拂去尘埃

 

A new space suit could resist the damaging effects of sharp lunar dust.

一款新型的宇航服能够抵抗尖利的月尘带来的破坏性影响。

"Picking up some dust." So said Buzz Aldrin on July 20th 1969, as he and Neil Armstrong descended towards the lunar surface.

1969年7月20日,Buzz Aldrin与Armstrong降落在月球表面,Aldrin对Armstrong说:"收集一些尘土。"

It is not the most famous quote from that day.

这句话并不是那天他们说的最有名的话。

"

 

dust sth down 拂去...的灰尘

 

But the lunar dust kicked up by Aldrin's and Armstrong's descending spacecraft would go on to become a serious, if under-appreciated, problem for all of the Apollo astronauts.

不过,Aldrin和Amrstrong驾驶的宇宙飞船着陆时扬起的月尘如果没有得到恰当的处理,会变成对所有阿波罗计划宇航员来说很严重的问题。

Lunar dust consists of rock pulverised to the consistency of talcum powder by micrometeoroid impacts.

月尘是由受流星体撞击影响而变成了滑石粉块的岩石组成的。

The fragments are sharp, and because there is no weather on the Moon, and therefore no erosion, they stay that way.

这些碎片十分锋利,并且因为月球上没有天气之说,没有腐蚀现象,故而它们会一直保持着自己的棱角。

At the same time, the solar wind bombards the dust with charged particles from the sun, giving it a static charge that makes it cling to anything it touches.

与此同时,来自太阳的太阳风让这些尘埃带上了正负电荷,有了电荷它们就能够依附任何它们触碰到的东西。

The jagged dust fragments blackened spacesuits, causing them to absorb too much heat.

由于这些锯齿状的尘埃碎片表面温度过高,接触到宇航服时会把宇航服烧焦、使其碳化变黑。

They scratched visors, hindering visibility, and caked batteries, making them overheat.

尘埃碎片还会划伤宇航服的面具,阻碍其视野,并且由于每粒尘埃都带有电荷,当它们彼此相连就相当于组成了电池组,开始加热。

Tramped back into the spacecraft, they escaped into the air, from where the astronauts had little choice but to breathe them in and risk any potential health consequences.

当宇航员回到太空飞船上之后,这些尘埃碎片就会分布在空气中,而宇航员们在不知不觉中被迫将它们吸入,这就对其健康造成了潜在的影响。

Half a century later NASA is pondering a return to the Moon, as a stepping stone for missions to Mars and the asteroids.

半个世纪后,美国国家航空和宇宙航行局将目光重新聚焦在月球上,因为月亮可以成为通往火星或是其他小行星的跳板。
